Detailed Description

The MTR105 is a dedicated rotating machine tester that brings Megger’s proven insulation resistance (IR) expertise together with advanced low resistance, capacitance, inductance, and rotation testing in one handheld instrument. It delivers a holistic view of motor health, enabling you to assess windings, connections, and overall condition with precision and confidence. Designed for production, service, and maintenance teams, the MTR105 supports fast, reliable decisions across your asset lifecycle.

Comprehensive testing capabilities

Built on a unified test architecture, the MTR105 consolidates multiple core measurements:

Insulation resistance with PI, DAR, timed tests, and temperature compensation for consistent, comparable results.
DLRO four‑wire Kelvin low resistance testing for accurate measurement of joints, connections, and windings.
Inductance and capacitance to characterise coils and diagnose imbalance or deterioration.
Motor direction of rotation and three‑phase supply rotation to verify correct installation before energisation.

This integrated approach reduces set‑up time, cuts the number of tools you carry, and streamlines workflows in the field or workshop.

Accuracy you can trust

Stable test voltages and four‑wire measurement techniques underpin consistent, repeatable readings. Temperature measurement and compensation keep IR results aligned to reference conditions, so trends are meaningful across seasons and sites. Clear, full‑colour graphics present values and trends at a glance, allowing you to validate pass/fail criteria and move decisively to the next task.

Safety engineered into every test

The MTR105 is designed to protect both operator and instrument. Fast live‑voltage detection inhibits tests if hazardous voltage is present, reducing the risk of damage when connected to energised circuits or across phases. User‑selectable test terminal lockout thresholds add another layer of control, while robust internal protection supports safe use in CAT III 600 V environments.

Robust by design, ready for the field

A tough, over‑moulded housing and IP54 environmental protection defend against dust, moisture, and daily knocks. Detachable, interchangeable leads adapt to different applications and maintain reliable connections. With onboard storage for up to 256 motors and simple USB download, you can capture, share, and analyse results as part of a connected maintenance ecosystem.

Confident, efficient decision‑making

By unifying essential motor tests in a single instrument, the MTR105 helps you shorten diagnostics, standardise procedures, and improve asset reliability. Whether you are commissioning new equipment, verifying repairs, or conducting routine maintenance, the MTR105 provides the clarity, safety, and durability you need to work with confidence.
